About this item
Product details
Product Features:
- Fully covered under a 10 year warranty - 10 times the industry standard of one year
- Quick, quiet flushing - American Standard toilets are famously efficient and hushed
- Industry-leading flushing system out-performs older toilets while using less than half the water
- Tank flushing components specially engineered to withstand chemically-treated urban water
- EverClean porcelain surface is extremely easy to keep clean
- Perfected porcelain casting process and adjustable tank anchors eliminate “tank wobbles”
- Straight-forward installation instructions are included with each tank
- 100% factory flush tested - guaranteed to perform
Champion 4 Flushing:
- Accelerator 4" flush valve - The flush starts with a piston action flush valve that lifts straight up, allowing water to pour into 4" valve opening from all directions. 1.28 gallons of water enters the bowl in less than a second - three times faster than standard 2" flush valves, and twice as fast as even performance 3" flush valves. The flush is quiet, too.
- 360 degree cleaning - Water entering the bowl does so in a sweeping 360-degree motion. This is designed to help completely clear the bowl, even while using less water.
- Powerful siphoning water jet - A perfectly positioned water jet captures the circular flow of water for optimal performance with minimal energy loss (water doesn’t hit a flat spot and slow down). As waste and water exit, they are siphoned into the trapway for an unmatched push/pull one-two punch.
- 2-3/8" fully glazed trapway - Waste and water exit the toilet through a trapway that is fully glazed, which seals it and provides for a smooth surface that waste can in no way cling to. The industry-leading 2-3/8” diameter chute also allows for solids with a nearly 70% greater mass exit without clogging.
Other Technologies / Benefits:
- EverClean Surface - Using the antimicrobial properties of silver (the precious metal), EverClean Surfaces inhibit the growth of bacteria, mold, and mildew. The super smooth, baked-in, mirror-like surface not only eliminates unsightly rings, but also helps repel toilet messes.

STAY CLEAR!!!
The toilet was installed less than a year ago. Recently, I began hearing sounds that the water was filling the tank. I popped off the lid and didn't realize the flush valve looked like nothing like any flap / seal in any other. Did a search on YouTube and it appear the failure of the seal is common. Contractor purchased this toilet, but I WOULD NOT HAVE. I now have to buy replacement seal > hire a plumber to repair - INCREDIBLE!!!
Hello Bruce450, Thank you for reaching out to American Standard. I’m sorry to hear your 4327A104 is leaking from the seal. I know that situation can be very frustrating. This model carries a ten year parts warranty with a copy of the purchase receipt. Please reach out to us using the Contact Us form or Chat option on our website, and an American Standard Consumer Connection Advisor will be happy to assist you. We are available Monday - Friday between 8AM - 7PM ET. Sincerely, Your American Standard Consumer Connection Team (americanstandard-us.com/contact-us)
